I have problems to get my new mobile phone (Sony Ericsson T630) connecting via infrared.

Beaming files betwen them via infrared works so it is no general hardware problem. And with my old mobile (a siemens) I had no problems, so I guess I have to adapt the init-sequences for the infrared connection.

Does anybody have this combination or an other ericsson phone working?

I do not find any hints on the internet opr in the manuals although looking for some days.
